option("cloudFiles.includeExistingFiles",”true”) will not work.

This option is responsible for processing the files in the folder when autoloader is started, so it matters only in the first run of autoloader and it is default to true.

Could you once again explain what you are trying to achieve?

Why do you want to reprocess the already processed files?

Do I understand correctly, that the requirement is to exclude the files from today?

In the code shared you say you are doing .load(blobName"/"+FolderName+"/*.json"), so it should pick up all the files that were not processed previously.
